OF SAME PLACE.

INDEPENDENT GAS-BURNER REGULATOR.

SPECIFICATION forming part of Letters Patent No. 537,294, dated April9,1895.

Application filed August 3, 1894.

To all whom it may concern.-

Be it known that I, JOSEPH KRAKER,a.citi Zen of the United States,residing in the city and county of San Francisco, State of California,have invented an Improvement in Independent Gas-Burner Regulators; and Ihereby declare the following to be a full, clear, and exact descriptionof the same.

' My invention relates to a device for reguro lating the How andpressure of gas.

It consists in a device attachable to each burner i'ndependentlyand incertain details of construction which will be more fully explained byreference to the accompanying drawings, in which- Figure l is a verticalsection. Fig. 2 is a perspective view of the Valve seat.

The object of my invention is to provide a device for regulating theflow of gas through zo each burner independently, so that whatever thevsize of the burner, a certainconsumption of gas within thecapacity ofthe burner may be assured. y

A is a casing of sufficient size to contain the valve B and the valveseat O. This cas-- ing has its lower end so constructed as to beproperly secured to the upper end of the supply pipe D through which thegas arrives at the burner.

From the top of the case is a tubular extension E having its exteriorand interior screw-threaded. Upon the exterior of this extension thegasburner tube F is screwed so that there is a tight joint between-thesupply pipe D and the burner tip, the gas being all delivered into theinterior of the casing A. The valve seat C is shown in the form of ahollow cone having a screw-threaded hollow extension O which is adaptedto screw into 4o the inner threads of the extension E at the top of thecase A, so that the valve seat will be situated a short distance abovethe open en d of the pipe D, and the openings through which-the gasflows into the case A.

The valve B is a light conical shell of similar shape to the valve seatC and adapted to fit within it when closed. This valve has a stem Gwhich extends up within the hollow extension O of the valve seat, andalso down 5o through a hole made in the part into which Serial No.519,360. (No model.)

the pipe D is securedso that the stem is suitably guided, andthe valveallowed to rise and fall at will.

The interior of the valve seatO has grooves H made'in it extending fromthe bottom up 55 to a point where they connect with the interiorpassage, for thel purpose of allowing a small flow of gas when the valvehas been closed.

The valve Bis so arranged with relation to the seat and the inletopenings, that under 6o a certain pressure of gas, the valve will remain open sufficiently .to allow the desired amount ot` gas to flowthrough the extension O ofthe valve seat and thence to the burner. Itthe pressure be increased, lthe valve will be closed against the seat O,but the grooves or channels H are designed to still allow the properproportion of gas to flow to the burner, under the increased pressure,so that whether the valve be opened or closed, the light fur- 7o nishedfrom the burner will be an even and steady one, and whatever increase ofpressure may take place within the supply pipe, no greater amount of gaswill be allowed to flow to the burner.

The upper end ot the extension C is so formed that a screw driver orother device may be applied to it, and it may thus be raised or loweredin the extension E into which it is moving the burner and adjusting thevalve f seat as previously described.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

1. An independent gas burner regulator, consisting of a closed casinghaving its lower end secured to the gas 'supply pipe, and a burnersecured to the upper end, avalve seat of conil cal form within saidcasing, having a hollow too extension adj ustably fitted to `the top ofthe casing, and a valve of conical form having a guiding stem adapted toenter said extension, said valve seat having grooves formed in its faceextending from the lower-edge to the apex and communicating with thehollow extension.

2. In a gas burner regulator, the combination, with the gas supply pipe,the burner and the chamber between said pipe and burner, of a conicalvalve seat and conical Valve adapted to close against the same, saidvalve seal; having grooves or passages in its inclined Walls connectingat one end with the chamber and at the upperl end with a hollowAextension from the valve seat, and said Valve having a stem adapted toen ter said extension and guide the valve.

In witness whereof I have hereunto set my hand.
